ＡＢＲ反应器是在ＵＡＳＢ反应器的基础上发展起来的，具有运行方式简单、管理方便、经济投入低及对生物量具有优良的截留能力和运行性能可靠等优点[1，2]。采用ＡＢＲ反应器对生活污水进行处理，使污水中大部分有机物得到降解，但是对氮和磷的去除效果较差，难以达到越来越严格的排放标准。为了脱氮除磷并进一步去除有机物，笔者采用ＳＢＲ作为后续处理，确定了最佳运行参数和对生活污水的处理效果。

图2 水力停留时间对ＣＯＤ去除效果的影响
从图2可见，在ＨＲＴ由30ｈ缩短至12ｈ过程中，对ＣＯＤ去除率和ＣＯＤ出水浓度影响不大；当ＨＲＴ降至10ｈ以下时，对ＣＯＤ去除率和ＣＯＤ出水浓度开始下降，因为停留时间太短，微生物完成对有机物的有效降解时间达不到；但当ＨＲＴ为36ｈ时，出水水质较差，主要原因是水力停留时间太长，上升流速超出一定范围后，反应器中的污泥可能会被过大的水力冲击作用而带出反应器，使得反应器内不能保持足够多的生物量，从而影响去除效果。在实际工程运用中，当反应器的容积已经确定，水力停留时间越小，单位时间处理的废水量越大，因此选择水力停留时间(ＨＲＴ)的参数为12ｈ，且在该参数条件下出水ＣＯＤ均小于100ｍｇ/Ｌ，且ＣＯＤ去除效果良好。
2．1．2 温度对处理效果的影响
固定ＨＴＲ为12ｈ，研究在不同温度下ＡＢＲ反应器对ＣＯＤ的去除效果，如表2所示。
从表2可以看出，随着水温的升高，ＣＯＤ去除率随之增加，温度的升高可以加快厌氧消化菌对有机污染物的分解速率，并能降低厌氧污泥混合液的黏度，这使污泥的沉降性能发生了变化，从而影响了出水的水质。温度大于16．0℃，ＣＯＤ去除效率大于70％，出水

图3 容积负荷对ＣＯＤ去除效果的影响
从图3中可看出，进水容积负荷在0．37～1．042ｋｇ/(ｍ3·ｄ)变化，随着容积负荷的增加，ＣＯＤ去除率逐渐增加，当容积负荷增加到0．69ｋｇ/(ｍ3·ｄ)时，ＣＯＤ去除率增加到80％，继续增加容积负荷ＣＯＤ的去除率变化不大，都在80％以上。说明当容积负荷在0．69～1．042ｋｇ/(ｍ3·ｄ)时，ＡＢＲ厌氧反应系统对容积负荷的冲击具有较好的适应性。
2．2 ＳＢＲ反应器处理效果的影响因素
2．2．1 厌氧时间对处理效果的影响
厌氧时间是影响磷去除效果的重要因素。磷的去除是通过聚磷菌在厌氧时释磷，在好氧时过量吸磷来实现的。磷的厌氧释放是好氧吸磷和除磷的前提条件，吸磷能力的大小取决于磷的厌氧释放情况。厌氧释磷越充分，聚磷菌贮存的能量就越多，到了好氧阶段吸磷效果就越好，出水的磷浓度就越低，处理效果就越好。污水中总磷浓度随时间的变化趋势见图4。
从图4可以看出，厌氧2ｈ聚磷菌放磷基本完毕，总磷浓度从6．12升至10．34ｍｇ/Ｌ。若再增加厌氧时间，放磷速度相当缓慢，因此确定厌氧时间为2ｈ。

从图5可以看出，在曝气1ｈ后ＣＯＤ降到50ｍｇ/Ｌ，已经能够满足城镇污水处理厂污染物排放标准(ＧＢ118-2002)中一级Ａ标准；曝气2ｈ后ＣＯＤ降到25．7ｍｇ/Ｌ；继续增加曝气时间对ＣＯＤ的去除效果基本不再增加。事实上由于ＡＢＲ工艺已去除大部分的有机物，所以ＳＢＲ在较短的时间内出水的ＣＯＤ就能达到排放的标准。从图6可以看出，曝气1ｈ，氨氮从23．5ｍｇ/Ｌ降低到19．7ｍｇ/Ｌ，去除率只有16．2％；当曝气时间在3．5ｈ以上时，氨氮浓度小于5．5ｍｇ/Ｌ。综合曝气时间对ＣＯＤ和氨氮去除效果的影响，确定曝气时间为3．5ｈ。
以前面确定的最佳厌氧、曝气时间确定ＳＢＲ的运行周期为10ｈ，进水2ｈ，曝气3．5ｈ，停曝搅拌2ｈ，沉淀1ｈ，排水0．5ｈ，静置1ｈ。

从表3可以看出，ＡＢＲ反应器对ＣＯＤ处理效果较好，出水ＣＯＤ<100ｍｇ/Ｌ，对ＳＳ也有一定的去除，去除率在70％以上；但是对氮、磷的处理效果较差，有时出水的氨氮和磷比进水的还高。采用ＳＢＲ进行后续处理，出水ＣＯＤ和ＳＳ达到城镇污水处理厂污
